1. To do things that create a very strong emotional reaction in one, especially anger, irritation, or exasperation. I hate Dave's new boyfriend, he's always trying to push my buttons, and he's doing a good job of it! No one will be able to push your buttons like your children, but it's all a part of the adventure of parenthood.

2. To be sexually attractive or arousing to one. A guy who knows how to cook really pushes my buttons.
